Hey Tom, this is Barry Sluder. You did a bunch of modification s on my Mokia about 2 years ago including replacing the wear ring. I’ve been extremely pleased with your improvements! They have definitely have made my boat more dependable and easier to use. My boat has been running great but it’s time to do a little maintenance.
I needed to resurface the ring even though I have not noticed a loss in power. So I tried to take the wear ring out by hand but it would not budge. I had to use the small screwdriver to break it free enough to work it out by hand. When I got it out I noticed the groove in the pump housing where the wear ring sits. The tip of the screwdriver is pointing at the grove in the picture. Like I said I have not noticed a loss of power but your guidance would be appreciated.
As while I’m asking, how often do you change the fuel and air filter. From what I have read you recommend a 5w20 synthetic oil 18oz or 300ml to the ring below the first threads of the oil fill. Please let me know your recommendations.
